To all whom it may concern.-

Be it known that I, JOHN W. STOIIJKIRANTZ,

of Buffalo, in the county of Erie and State of New York, have invented anewand useful Improvement in Derricks, of which the following IS aspecification.

This invention relates more particularly I to a derrick for transferringrails or freight from cars running on a dock to a boat arranged alongthe side of the dock, although the same may also be used for otherpurposes. The object of this invention'is to provide a derrick of thischaracter which permits of "condition for trans ortation. Fig. 7 is ascale,

readily and expeditiously transferring freight. from cars on the dock toaboat, or vice versa,

with a mimmum number of attendants and with the least wear on theworking parts of the derrick.

In the accompanying drawings, consisting of five sheets, Figure 1 is aside elevation of my improved derrick. Fig. 2 is a front elevation'of-one-section thereof. Fig. 3 is a sectional elevation, on an enlargedscale, showing oneof the clamps on amast-care riage. for holding thederrick against horizontal movement when the same is made portable. Fig.4 is a top plan view of one section of the'derrick. Fig. 5 is a top planview, on a reduced scale, showing two sections of the derrickarrangedfor delivering rails or freight from a dock to,a boat alongside of thedock. Fi 6 is a horizontal section taken in line 6 6, ig. 1, but on thesame scale as. Fig. 5 and showing the derrick in fragmentary front eevation, on an enlarged showing the means for connecting the carriaawfragmentary side elevation of the lower part of the derrick, showingthe means for temporarily connecting a mast-supporting es which supportthe lower ends of the ,two a jacent masts of the derrick. Fig. 8 is tnedrawings the derrick is represented in 1ts most complete form in whichthe same is capable of being transported lengthwisev from one partbf thedock to another to meet different conditions; but, if desired, thesamecomprises one or more sections each of which consists, essentially,of a horizontallyrotatin'g mast B, arranged on the dock between the edgethereof and the front side of the trackway or loading-space; a boom (1,pivotally connected at its inner end to the lower part of the mast andcapable of being raised and lowered; an upright stage D, arranged on thedock in rear of the trackway or loading-space; a bearing 6, in which thelower end of the mast is journaled;. a bearing 1), in which the upperend of the mast is journaled; a central tie bar or brace E, extendingtransversely from the top hearing I) to the central upper part of thestage, and two side tie bars or braces E E extending transversely andobliquely from the top bearing 1) to the upper part of the stage onopposite sides of the central tie bar or brace.

The turning of the mast is effected by means of a swinging line or cableF, which passes with its central part around a bull or swinging wheelarranged at the upper end of the mast, while its opposite ends are woundaround the swinging drums g g of a hoisting- -machine G, which ismounted on an elevated platform H on the stage. This hoisting-ma-- chineis arranged at one end of the platform adjacent to the rear end of oneof the oblique tie-bars, and the two parts of the swinging cable passobliquely upward from the swinging drums around guide-wheels I I, whichare mounted on the stage adjacent to the junction of its top with therear end of the other oblique tie bar or brace, and then pass along thislast-mentioned tie-bar around intermediate guide-wheels i i on thelatter to the hull-wheel, as shown in Figs. 1, 2, 4, and 5.

The boom is raised and lowered by means of a boom line or cable J,operatively connected at one end with the outer end of the boom, whileits opposite end is wound around the boom-drum j of thehoisting-machine. The intermediate part of the boom-cable passes over aguide-wheel k on the upper caring of the mast, thence obliquely along 55their booms over ditlerent parts ofthe'boat,

the tie-bar E and around a guide-wheel 7c, arranged at the junction ofthe tie-bar E and the stage adjacent to the guide-wheels I I, and thenceobliquely downward to the boomdrum of the hoisting-machine.

The load to be transferred from the dock or cars to the boat, and viceversa, is raised and lowered by means of a tackle or tackle-hook L,adapted to be connected with the load, and a hoisting-cable or main lineZ, operatively connected at one end with the tackle and passing with itsopposite end around the oisting or main drum M of the hoisting-machine,while its intermediate part passes around a guidewhcel m at the outerend of the boom, a guide-wheel m at the lower end of the mast, aguide-wheel m on the upper bearing of the mast, and a guide-wheel m onthe stage adjacent to the junction between the same and the obliquetie-bar E, that part of the cable Z between the guidewheels m m beingarranged obliquely and along the tiebar E? and that part of the samebetween the guide-wheel m and the main drum M being arrangedsubstantially parallel with the adjacent oblique parts of the boom andmast cables. By thus arranging the guid'e-wheels I 1 k 'm of the severalcables at the junction of the stage and the oblique tie-bar E thesecables pass in a directline from these guidewheels along the saidtie-bar to a point adjacent to the upper end of the mast and also in adirect line to the several drums of the hoisting-machine, therebyreducing the number of guide-wheels for these cables between the mastand the hoisting-machine to a minimum and reducing the wear upon thesecables accordingly.

The platform H is preferably higher than the top of the load on thecars, and the hoisting-machine is arranged on one side of the 'mast,which enables the attendant ofthe hoisting-machine to observe themovement otthe load during its entire passage or transfer from the carsto the boat, or vice versa, thus facilitating the operation of loadingand unloading and reducin the number of attendants which is usuallyrequired for this purpose.

When a derrick of small capacity is required, a single section of myimproved der ick, as shown in Fig. 4, will answer the pur pose. Forloading boats of considerable length it is preferable to employ twoderricks side by side, as shown in Fig. 5, and swing whereby loading andunloading of the same are facilit ated. When these derricksare thusemployed, the stages of the same ar connected so as to form practicallyone structure.

In order to permit of trans orting the derrick from one part oi toedock'to another for adapting the safne to the position of the hatchwaysor other conditions, the stages is in use.

ea aces are, provided on their under sides with supporting-wheels 0,which run on longitudinal tracks or rails 0. The lower mast-bearings bare provided with supporting wheels 1), which run on longitudinal tracksor rails p, and the lower bearings b of the two masts are connected by ahorizontal beam or bar N, which is provided with the wheels or rollersn, running on the tracks 12. The lower parts of the lower mast-bearingsand the stages thus form carriages, which support the mastsandhoistingmachines and the parts connected with the same.

In order to hold the lowermast-bearings and the masts in positionrelatively to the stages while transporting-the same, movable obliquebraces orcoupling-bars Q- are employed, each of which is preferablypivoted at its rear end to the lower part of one of the stages and detachahly connected with one-of the mast-carriages by means of a pinq,passing through corresponding openings in these In Fig. 6 these bracesare shown in for coupling the insist-carriages with the stagespreparatory to shifting the derrick bodily on the dock. After thederrickhas been thus shifted the coupling-bars are detached at theirfront ends from the mast-carriagesand folded rearwardly against thestages, as shown by dotted lines-in Fig; 6, in which position these barsare supportedby hooks or brackets r on the stages and leave loaded andunloaded cars into and out of the loading-space between the masts andthe stages.

- the main loading-tracks clear for moving the IOQ Any suitable meansmay be employed for holding the stages and mast-carriagesagainstmovement on their'tracks when the derrick The preferred means forthis purposelshown in Fig. 3) as applied to a mastcarriage consist ofclamping-screws S, mounted in brackets s on the mast-carria es apair ofinclined claws t,pivoted at thelower end of the clanipin -screw; a linki, embracing these claws an with their hooks underneath opposite sidesof the adjacent rail-head, and a clamping-nut it, applied to theupperendof the'clamping screw and bearing against the-upper side of thesupporting-bracket sf; For the purpose of freeing this clamping "devicefrom the track and permitting the derrick to be moved horizontally thenut a is first unscrewed and then the link t is moved upoperatingto-hold the same Wardly, thereby releasing the claws from the rail andpermitting shitting of the derrick along its tracks. r
